目的：探讨利用胸腔镜在进行肋骨骨折内固定手术时对手术切口的精确定位的效果及可行性。方法回顾性分析28例肋骨骨折合并血气胸的患者在进行肋骨骨折内固定手术采用胸腔镜辅助精确定位胸部切口的病例资料，并与同期23例行传统剖胸肋骨骨折内固定的患者病例资料相比较。结果与行传统剖胸肋骨骨折内固定术的患者相比，胸腔镜组在切口延长次数上明显减少(P<0.05)。结论胸腔镜可精确定位肋骨骨折内固定手术切口，避免术中延长切口，具有减少组织损伤等优点，值得临床推广。“,”Objective To investigate the ef ect and the feasibility of precise positioning of the oprative incision on rib fractures repair by thoracoscopy. Methods Retrospective analysis 28 patients of rib fractures combined hemopneumothorax of precise positioning of the oprative incision on rib fractures repair by thoracoscopy and rib fractures repair by traditional thoracotomy. Results The quanlity of oprative incision to lengthen lesser than the rib fractures repair by traditional thoracotomy( P<0.05). Conclusion Thoracoscopy can accurately locate the oprative incision and less injury of tissue. It is worth to popularize.
